i like the "organic" look it gives the tsuka. Nice idea.
First i thought you had covered it in (Don`t remember the english name for it) the kind of black plastic/rubber hose you put on electrical wires and shrink with heat. But understood i was clearly wrong when i read the text ;-) Hm...maybe i should use the plastic/rubber hose on a future project...?...lol.
Have a nice day
